Abstract :
The adaptive mesh model is extended in several ways. Open adaptive meshes and closed adaptive shells based on triangular and rectangular elements are developed. A discontinuity detection and preservation algorithm suitable for the model is proposed. Techniques for adaptive hierarchical subdivision of adaptive meshes and shells are also developed. The extended model is applied to image and 3D surface data
